Abstract: A method for processing a video signal and a method for calibrating signal processing apparatuses are disclosed. The method for video signal process comprises the following steps. First, an analog video signal having a sync pulse is provided. Then, a peak level of the sync pulse is detected, and a signal transfer gain is determined based on the peak level of the sync pulse. Finally, the analog video signal is converted into a digital signal according to the signal transfer gain.
